Boston Market (Improved Early Paris).—This variety, which has now gone out of existence, was formerly extensively cultivated around Boston, where it originated by continued selection from the Early Paris. In the American Journal of Horticulture, for 1869, p. 92, is a figure and description.
Burpee's Best Early.—An improved type of Dwarf Erfurt, named and introduced by W. A. Burpee & Co. in 1886, after, as they say, sixteen years selection by one grower. It is said to be of dwarf, compact growth, with a short stalk, and large, solid, nearly globular heads, very early and certain to head.
The Dingee & Conrad Company sell the same variety.
At the Ohio experiment station in 1889, this variety was regarded as probably the same as Large Erfurt, rather large, and a few days later than Early [Extra Early] Erfurt, but quite as good in other respects. At the Colorado station, in 1888, "Burpee's Earliest" was noted for its large leaves and white, compact heads. It headed ten days later than Henderson's Snowball.
Carrara Rock.—An extra selected strain of Erfurt, said by Wm. Elliott & Sons, of New York, to be the earliest and surest variety to head.
Carter's Defiance (Early Defiance).—Gregory considers this a fine variety for forcing or very early use.
Carter's Dwarf Mammoth.—An early variety, coming in just after Carter's Defiance. Plant dwarf, head very large, perfect in form and of fine color.
Carter's Extra Early Autumn Giant.—A variety said, in 1889, to have large, close, white heads, both flower and leaf being less coarse than those of Autumn Giant.
Carter's Mt. Blanc, see Mt. Blanc.
Chalon Perfection. A variety mentioned in Gardener's Monthly, in 1886. Said to be as white as snow, almost as smooth as ivory, and to make good heads in soil of moderate fertility. Probably the same as Early Dwarf Chalon, which see.
